Create a Python program that emulates a Banyan-Batcher network with 8 inputs and 8 outputs and then scale the output to a 16 x 16 Delta Network. Use a random generator with 8 (or 16) options to emulate the input table routing list with the assigned input port. Show that your simulation works for all inputs and all outputs. Explain how network routing fabric changes when you have 16 inputs and 16 outputs. Please make sure you are posting a Python script. The last answer was not effective.
Abstract: the main purpose of this experiment is build real time system using PPI 8255 to control devices connected to. Problem description: assume that there are two devices are connected to port A and two sensors are connected to port B of PPI 8255. They work according to the following table Sensors (S1S2) Devices (DID2) 00 01 01 10 10 11 11 00 Write a program to control these two devices according to the values of sensors.

Wireless sensor networks (WSNs) are a specific sort of communication network. WSNs communicate with a central station through sensor nodes. A sensor node's memory and processing power are limited. The algorithm may be split down into simpler challenges. Divide & conquer or dynamic programming are your preferred methods for completing these sub-problems at various sensor nodes?

Consider a paging system with the page table stored in memory.a. If a memory reference takes 400 nanoseconds, how long does a paged memoryreference take?b. If we add TLBs, and 95 percent of all page-table references are found in the TLBs,what is the effective memory reference time? (Assume that finding a page-table entry inthe TLBs takes zero time, if the entry is there.)
A paging scheme uses a Translation Look-aside Buffer (TLB). A TLB-access takes 10 ns and a main memory access takes 50 ns. The effective access time(in ns) is_?(if the TLB hit ratio is 90% and there is no page-fault)

Suppose a computer system uses 16-bit addresses for both its virtual and physical addresses. In addition, assume each page (and frame) has size 256 bytes. How many bits are used for the page number? How many bits are used for the offset? With this system, what’s the maximum number of pages that a process can have? Suppose that each entry in the page table comprises 4 bytes (including the frame number, the valid bit, and miscellaneous “bookkeeping bits”). An OS uses an array to store the page table. What is the size of the page table? Furthermore, suppose the first 6 pages of a process map to frames 222 to 227 (as decimal numbers), and the last 5 pages of the process map to frames 1 to 5 (also decimal numbers). All other pages are invalid. Draw the page table, including the valid bit and the frame number.
